Oled display not working, show Black Screen after-show dots

[luqman]

Hi.

I'm new on this form and also new on nrf dev board. I want to use OLED with nrf52832 using Twi / i2c. I grab some code on Github https://github.com/monpetit/nrf52-spi-i2c-master-ssd1306

which is running on my SDK 16.0. But the Oled now shows not any full response on this code just show some dots on the screen when I upload the code and after that, it's going dark 

I try using the TWI_scaner example which shows me the address 0X3C

as well but I don't have a logic analyzer to check the states of pins so if one knows the solution please let me know. 

thanks.

Great to hear that you got it working. If you get the chance,sharing the solution could be helpful for others.

Please let me know if you still need help getting any of the other solutions up and running.

Hi luqman,

Sorry for the delay regarding mesh. To get started you may follow the documentation for the nRF5 mesh stack: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v5.0.0/md_doc_getting_started_getting_started.html?cp=7_2_1

You may then start with the light switch example:

If you get stuck, open a ticket and you will get a reply from someone more experienced with mesh than I.

Best Regards

Håkon
